Question about 1993 Isuzu Rodeo
I have a knock in the front end of a 1993 isuzu rodeo when in 4 wheel drive, only when going up hill. I've also had problems w/ the auto locking hubs disengaging. Could this be related? How do I install manual hubs?
Your problem may be as simple as a bad ball joint, CV joint, tie rod end, hub assembly or other front end part. Something is not tight anymore. Have the front end checked and go from there. GOOD LUCK FRIEND.

Just have your auto - locking hub cleaned and use your 4wd more often, it get stock usually for non usage. dont use grease after cleaning, use oil or thick silicone oil.

I've had the same situation. I found the problem to be the Hi-Lo gear shift was not locked in place. In other words, it was between Hi and Lo. While the truck was off, I moved the gearshift from Hi back to Lo back to Hi, making sure it was in Hi gear. Then, after starting the car and traveling down the road, I found that the 4WD would disengage with the button.

Hello scotch1812, those of us that still enjoy the square headlights have to stick together! The front axle in our YJ's are dana 30 with a high pinion! The high pinion make the ring and pinion spin in a reverse rotation from the dana 30 found in CJ and TJ Jeeps. When Chrysler designed the YJ front axle, they removed the manual hubs like those found in CJ models and installed a vacuum disconnect on the passenger side axle shaft. The passenger side axle shaft is 2 piece with a sleeve that is moved into place to connect the 2 pieces of axle shaft when you shift the transfer case into 4 wheel drive. This is done via a vacuum module mounted on the axle housing. If your module diaphram goes bad you have no 4WD! If your vacuum hose comes off of the module or breaks you have no 4WD. Now when your transfer case is in 2WD the front driveshaft does not turn. The vacuum disconnect allows this to happen. As for the hubs, they are simply hubs with sealed bearings and a universal joint to allow your front wheels to turn left and right. If you hear the banging noise in 2WD it could be a bad universal joint in one of your axle shafts.
Now if you are hearing the banging noise only when you are in 4WD there could be a number of reasons. You could have a broken axle shaft or a bad bearing in your ring and pinion. Your front driveshaft could be bent or at least not straight. I would start with the driveshaft. Just lay under the Jeep (Not running! With emergency brake set!) and spin the front driveshaft. If it spins true and doesn't have an out of round rotation we can rule that out! Also, grab it and push it and pull it to check to see if your universal joints in the drive shaft are gor and tight! They can make a grinding noise or popping noise if they are bad!
Try these and let me know what you find! We will find your problem!

They are operated by vacuum. Check to make sure the vacuum lines are connected and not ripped or anything. If that checks out fine, remove the vacuum line from the hub and apply vacuum to the hub, if the hubs lock then the problem is in the vacuum line or switch.
